CUTTER-HEAD.

Specification of Letters Patent.

Patented Oct. 31, 1905.

Application filed July 15, 1905. Serial No. 269,804.

To all whom it may concern:

Be it known that we, JOHN WILSON WARD and WILLIAM A. WILLIAMS, residingat Bolton Landing, in the county of Warren and State of New York, haveinvented certain new and useful Improvements in Cutter-Heads, of whichthe following is a specification.

Our invention, which in its generic nature relates to improvements incutter-heads. usually termed matcher-heads, of that character mountedupon a vertical spindle and carrying the cutters for effecting thetonguingand-grooving operation for flooring and ceiling material, moreespecially seeks to provide an improved means for effecting a largenumber of different adjustments of matcherheads for setting the samerelatively to the different thicknesses of lumber to be formed with thetongues and grooves.

Our invention generally comprehends an improved cooperative arrangementand combination of a plurality of washers or disks re- Versibly side forside, individually and collectively, whereby to provide for a largenumber of adjustments of the cutter or matcher head; and in itssubordinate features it consists in the detailed construction of partshereinafter fully explained, specifically pointed out in the claims, andillustrated in the accompanying drawings, in which Figure 1 is avertical section of the ordinary type of matcher-head, for which ourinvention is the more especially adapted, mounted on the drive-spindlewith our improvement applied, showing the same adjusted to effect thefirst or initial adjustment of the matcher-head. Fig. 2 is a similarview showing the parts arranged for effecting a second adjustment. Fig.3 illustrates how the parts shown in Fig. 2 are arranged to effectathird adjustment. Fig. 4. illustrates the mannerin which our inventioneffects a fourth adjustment. Fig. 5 illustrates how the parts shown inFig. 4 are arranged to effect a fifth adjustment. Fig. 6 shows thearrangement of the parts for effecting a sixth adjustment. Fig. 7 showsthe parts arranged to effect a seventh adjustment. Fig. 8 shows how theeighth adjustment is secured.

In the practical application of our invention we employ a cup-shapedmember 1, whose bottom is of a thickness sufficient to'effect a first orinitial adjustment of the matcher-head when the cup is positioned asshown in Fig. 1. This cup, which in a general sense has the function ofa washer, in our invention is made of a depth sufficient to receive aplurality of other similar washers and also to provide for apredetermined or maximum thickness, whereby when positioned as shown inFig. 8 the maximum adjustment or eighth adjustment of the matcher-headis efiected, as hereinafter more fully explained.

2 designates a second disk or washer of less diameter than thecup-shaped washer so it can be readily slipped into the member 1 when itis positioned as shown in Fig. 1. This second washer has one side orsurface in a smooth unbroken plane, as designated by 2, while its otherside is recessed, as indicated by 2 whereby to form a washer portion ofpredetermined thickness sufficient when the disk 2 is positioned withinthe cup 1, as shown in Fig. 2, its thickness and the thickness of thebottom of the cup, as indicated by the broken line a on Fig. 2, producea combined thickness of washer or filling to effect a second adjustmentof the matcherhead. The major thickness of the washer 2 (that is takenthrough the annular rim 2 thereof) is of such predetermined nature sothat when the said washer 2 is turned over, as shown in Fig. 2, itsmajor thickness, combined with the thickness of the bottom of the cup,presents a filling or washer thickness suflicient to effect a thirdadjustment of the matcher-head.

3 designates a third washer, similarin shape to washer 2, but having itsminor and major thicknesses of a greater thickness than that of themember 2, in practice being so determined that when the washer 2 isremoved from cup 1 and the member 3 is positioned therein, as shown inFig. 4, with its minor thickness between the upper end of the spindle Sand the lower end of the clamp-screw C, a sufficient washer-filling isprovided between the screw C and the spindle S to effect a fourthadjustment of the matcher-head, the major thickness 3 of said disk 3being such that when the said disk is turned over in the cup 1 andpositioned as shown in Fig. 5 a fifth adjustment of the matcher-head isprovided for.

By reason of the variable thicknesses of the members 2 and 3 and theirrelative individual major and minor thicknesses by's'eat'ing, the

thin washer 2 with its annular flange up, whereby to combine the minorthickness-of saidwasher 2 with the major thickness of the member 3, asufficient filling is provided between the screw C and the spindle S toeffect a sixth adjustment of the matcher-head, and when the said thinwasher 2 is turned over and positioned as in Fig. 7 the major thicknessof said washer 2, added to the major thickness of the washer 3, effectsa still greater filling between the screw G and the spindle S, and thisprovides for a seventh adjustment of the matcher-head. It will benoticed that in all of the adjustments of the washers 2' and 3 mentionedwithin the cup 1 the major thickness of the cup is through the annularflange portion thereof, and the said major thickness is greater than thecombined major thickness of the members 2 and 3 and the minor thicknessof the cup, and by reason of such arrangement of parts by removing themembers 2 and 3 from the cup 1 and turning the said cup upside down amaximum filling is provided for between the spindle and the screw 0, andthus an eighth adjustment of said head is effected. I

We are aware that a cup-shaped washer has been provided capable of beingreversibly mounted between clamp-screw and the spindle for effecting twoadjustments of the matcher-head. Our cup-shape member differentiatesfrom what has been heretofore provided in this art, so far as we know,in that it provides for the minimum or first. adjust ment of thematcher-head, the final (eighth) or maximum adjustment of the same, asalso a cooperative part of the means for effecting all of theadjustments between the first and the last.

While we have shown a means consisting of three washers, each having amajor and a minor thickness, each independently reversible and the threecooperatively adjustable, additional washers, like 2 and 3, might beprovided with a cup 1 of proper depth to effect further adjustments byindividual adjustments of the said additional washers and a combinedadjustment of the same with the Washers 2 and 3.

. By reason of the peculiar construction and combination of the partsdescribed and illustrated the advantages gained in using our inventionin handlin stock for tonguing and grooving will be clearly a parent tothose skilled in the art to which t 's invention appertains. Theindividual and collective reversals of the members 1, 2, and 3 readilyprovide for setting the matcher-head to eight different adjustmentscapable of working on eight different thicknesses of material andeffecting" an accurate operation of tonguing and groovin v Havingthusdescribed our invention, what we claim, and desire to secure by LettersPat-" exit, is

1, A means for adjusting matcher-head cutters, of the characterdescribed; comprising a plurality of washers each having a major and aminor thickness, adapted to be interposed between the bearing portion ofthe head and the spindle end, said washers being adapted to beindependently reversed or collectively reversed with respect to thespindle end whereby to provide for a plurality of adjustments of thematcher-head cutter, one of said washers adapted to contain theremaining Washers as set forth.

2. The combination with a matcherhead cutter, its carryingspindle andits clamp-screw; of a plurality of washers of such construction, wherebywith the presentation of one side or surface thereof in the direction ofthe screw, a different adjustment is obtained from that obtainable bythe presentation of the opposite side of the said washer members to saidscrew, and whereby the presentation of one surface of one washer, andanother but difierent surface of another washer relatively to theclamp-screw and spindle effects still further adjustments, one of saidwashers adapted to contain the re maining washers as set forth.

3. The combination with a matcherhead cutter, its carrying-spindle andits spindle engaging screw of a cup-shaped Washer, adapted when turnedwith one side to the screw to effect one adjustment, when turned overwith the other side to the screw to effect another adjustment, andanother washer removably mounted in the cup, having a major and a minorthickness, adapted when turned over to bring its opposite sides to thespindle-screw to effect a plurality of intermediate adjustments.

4. An improved means for adjusting matcher-head cutters, which consistsin combination with the matcher-head spindle and its clamp-screw, of acup-shaped washer adapted to be reversiblypositioned between the screwand spindle, a plurality of washers adapted to be independently seatedwithin the said cup, and collectively interchanged, said washers eachhaving a minor and a major thickness, and having a combined majorthickness less than the major thickness of the cup in Which they areheld.
